Second-Harmonic Generation (SHG)
QTekLaserTM offers laser systems with extended wavelength range by combining nonlinear frequency conversion technologies. Through second-harmonic generation (SHG) we achieve significant laser power at the visible and NIR regime (figure 2; red-shaded cells of table 1). With the development of periodic poled crystal technology and the associated waveguide technology, nonlinear frequency conversion has become a powerful tool to extend the application scope of fiber lasers. For QTekLaserTM products, the max power of the converted laser light is constrained by the damage threshold of commercially available nonlinear crystals, which is typically several tens of watts.

QTekLaserTM lasers comply with Federal Regulations (21 CFR Subchapter J, Part 1040) as administered by the Center for Devices and Radiological Health and are certified to IEC 60825-1:2014 standards.
It is the end user's responsibility to ensure that no significant light is retroreflected back into QTekLaserTM systems as this can degrade performance and potentially damage the lasers. To prevent this, the use of an external optical isolator is strongly recommended. Damage due to retroreflected light is not covered under warranty.

Quantum Applications
In the near-IR, the 783 nm laser is well suited for neutral-atom quantum platforms using rubidium and cesium. Its narrow-linewidth, low-noise output supports optical-lattice and dipole trapping of ultracold rubidium, as well as blue-detuned nanophotonic traps for cesium atoms near optical waveguides, enabling precise atomic confinement, coherent manipulation, and atom–photon interfaces for quantum computing and quantum networking.
